title: Erosive tooth wear: prevalence and severity in Swedish winetasters.
abstract: Full-time Swedish winetasters test on average 20-50 different wines, nearly 5 days a week. As the pH of wines ranges from 3.0 to 3.6, there is a potential risk for tooth erosion. The aims of this study were to document the prevalence and severity of tooth erosion in qualified winetasters in relation to number of years of winetasting, salivary flow rate, and buffer capacity. The subjects comprised all 19 qualified winetasters (7 women and 12 men, aged 29-64 years employed in Stockholm by Vin & Sprit AB, the state-owned company marketing wines and spirits. At intraoral examination, tooth surface loss was registered and documented by photography. Salivary flow rate and buffer capacity of unstimulated and stimulated saliva were measured. Data on occupational background and dental and medical histories were collected. Fourteen subjects had tooth erosion, the severity varying from mild to extreme, mainly on the labio-cervical surfaces of maxillary incisors and canines. The severity of the erosion tended to increase with years of occupational exposure. Caries activity in all subjects was low. 14 subjects had low unstimulated salivary flow rates. It was concluded that full-time winetasting is an occupation associated with increased risk for tooth erosion.
